Surly 16T Silver Fixie Cog – 3/32″ Chain Compatible

Surly Track Cog – Precision-Grade BMX & Single-Speed Compatibility

Engineered for fixed-gear enthusiasts and track riders, the Surly Track Cog delivers reliable performance with its hardened 415 chromoly steel construction. Designed with BMX freewheel threading (1.375″ x 24 TPI, right-hand), it fits single-speed rear hubs and BMX freewheel hubs—though optimal performance is achieved on dedicated track hubs for safety and durability.

Key Features:
– 16-tooth configuration for balanced speed and control in urban commuting or velodrome racing.
– High-strength chromoly steel resists wear, extending lifespan under heavy use.
– Universal threading offers flexibility for experimental builds (note: track hub use recommended).

Why Choose This Cog?
Unlike generic cogs, Surly’s precision machining ensures consistent engagement with your chain, reducing slippage during high-torque sprints. Ideal for fixie riders, bike messengers, or DIY builders seeking a rugged, low-maintenance drivetrain component.
